Abstract:
The invention is about E. coli host cells which are capable to convert glycerol to serinol. Furthermore, a process for producing serinol is disclosed, which comprises culturing E. coli host cells inactive for triosephosphate isomerase and active for dihydroxyacetone phosphate aminotransferase to convert glycerol to serinol, induction of conversion from glycerol to serinol by adding at least glycerol to the cell culture, and isolating serinol from the cell culture.
Abstract:
The aim of the invention is to increase the product yield of protein in microbial fermentation. Said aim is achieved by a method in which, in addition to a first expression construct coding for the protein, a second expression construct is introduced in a microorganism, which second expression construct codes for an auxiliary protease that differs from the protein, is proteolytically active and comprises an amino acid sequence, which is at least 50% identical to the amino acid sequence provided in SEQ ID NO. 1.
